Users who choose to opt-in to this process can access the newly built
packages, as soon as they are exported from the build system after some
basic testing has been completed. They are less comprehensively reviewed
in the QA validation stage than the full release (Note: "Less
comprehensively" does not mean no QA testing ... it just means less than
the full release).

Some packages, like the anaconda installer, routinely receive updates
during the full QA process, and the final versions may be updated from
the CR version.

Known issues:
1. sssd-common is no longer multilib in CentOS 6.7. If you have the
32bit sssd-common installed on your x86_64 system, you will need to
remove it with yum remove sssd-common.i686 prior to updating.

2. The boost RPMs are built with cmake-2.8 and the configuration files
produced cause issues building some source code. There are an upstream
bugs here (which is likely NOT being fixed):

3. The satyr package from EPEL is newer than the version included in
CentOS-6.7. The package from EPEL seems to work OK as well, but they
are likely to remove it as it also conflicts with RHEL-6.7. We have not
observed any negative impacts from this issue.

4. yum-plugin-downloadonly has been obsoleted by yum, and the
functionality is now built into the default yum.

More information:
1. These CentOS packages are built from the RHEL-6.7 source code
released by Red Hat on July 22, 2015. Please review the release and
